Constituent-Quark Model and New Particles

An elementary constituent-quark (CQ) model by Mac Gregor is reviewed with currently published data from light meson spectroscopy. It was previously shown in the CQ model that there existed several mass quanta m = 70 MeV, B = 140 MeV and X = 420 MeV, which were responsible for the quantization of meson yrast levels. The existence of a 70-MeV quantum was postulated by Mac Gregor and was shown to fit the Nambu empirical mass formula mn = (n/2)137me, n a positive integer. The 70-MeV quantum can be derived in three different ways: 1) pure electric coupling, 2) pure magnetic coupling, and 3) mixed electric and magnetic charges (dyons). Schwinger first introduced dyons in a magnetic model of matter. It is shown in this paper that recent data of new light mesons fit into the CQ model (a pure electric model) without the introduction of magnetic charges. However, by introducing electric and magnetic quarks (dyons) into the CQ model, new dynamical forces can be generated by the presence of magnetic fields internal to the quarks (dyons). The laws of angular momentum and of energy conservation are valid in the presence of magnetic charge. With the introduction of the Russell-Saunders coupling scheme into the CQ model, several new meson particles are predicted to exist. The existence of the f0(560) meson is predicted and is shown to fit current experimental data from the Particle Data Group listing. The existence of meson partners or groupings is shown.
